Development of retrospective dosimetry using pulsed optically stimulated luminescence

本文研制了脉冲光激发光（POSL）测量系统。该系统用于性能测试。将该方法应用于已知剂量土壤的剂量回收试验，结果表明，该方法可用于POSL剂量学，其检出限高于预期值。由于样品中石英含量相对较少，该方法前处理简单.但剂量学方法可将预处理时间从3天缩短到数小时。

Pulsed optically stimulated luminescence (POSL) measurement system was developed in this research. The system was used in the performance test. Moreover, the method was applied to dose recovery test using a known dosed soil.From the results, the POSL dosimetry could be developed with higher detection limit than the expected value. The method needed the simple pretreatment procedure because the sample had relatively small amout of quartz. However, The dosimetry could shorten the pretreatment time from 3 days to some hours.
